Selecting your vehicle in the Ohme app lets us know which EV is charging, as well as the battery size, range, and maximum speed at which your EV can charge. All of this information is important to make sure that Ohme charges your EV correctly. To ensure your charge session is accurately calculated, it’s important to select the correct car before you plug in. Below is a short step-by-step for how to switch cars in the Ohme app. If you’re connecting your car account, there will be a few extra steps to complete.

Creating a custom car
Pairing your Ohme account with your car app account
When charging multiple cars on the same account, it’s important to ensure you have the correct car profile selected before you plug in to charge. If you have multiple EVs to charge, with App Version 2.4.0 or later, you can save different vehicle profiles and toggle between these easily.
You can then see which car you have selected on the Charging page in the top left.
For more information on charging with multiple EVs, please see this support article: https://ohme-ev.com/support/how-can-i-charge-multiple-vehicles/
If your EV brand or model isn’t available as a pre-set option, you can create a custom car profile. By setting the battery size, charge rate, and maximum range, you can customise the profile to match the specifications of your vehicle. This allows for a more personalised and accurate representation of your car’s capabilities and charging needs. Let’s dive in and explore how you can make the most of this feature.
To start, click the Settings button along the bottom of the Ohme app and tap My EV, or click the existing vehicle profile listed in the top-left corner of the Charging page of the app.
Then tap ‘Add an EV’.
Next, tap the My brand isn’t listed button at the bottom of the screen.
You’ll then need to add the specifications of your car. If you’re unsure, refer to your paperwork from your original purchase or the car handbook. We will require the following information:
Brand and car model name (e.g. Fiat 500e)
This will be shown as the title of the car on the My EV page.
The battery size in kWh (e.g. 42kWh)
The battery size is important for Ohme to know how much time it will need to schedule to fill the battery.
The maximum AC charging speed in kW (e.g. 7.68kW)
The rate of charge is also important to help Ohme understand how much time it will need to schedule to fill the battery.
The maximum range (e.g. 199 miles)
The range will help to provide an estimation of how much range the car may achieve by the end of the session. Note: Only the car itself (or car app) will be able to show the true range the car can achieve.
Once you have added all of the specifications, tap Confirm to finish.
Once you have added your vehicle details and tapped confirm, you are all set up. Tap done to return to the My EV page.
You can edit your custom car specifications from the My EV page by tapping ‘Edit tech specs’.
Some car manufacturers provide an API (Application Programming Interface) which allows access to information about your car via your manufacturer’s app. Providing your login details in the Ohme app allows Ohme to see your car’s current state of charge, which is then used to work out how much charge you need. This feature is currently available for a limited number of brands. If your brand isn’t listed, Ohme won’t be able to see your car’s state of charge. API support is currently available for the following brands:
Audi
BMW
Cupra
Hyundai
Kia
Mini
Nissan
Renault
Skoda
Tesla
Volkswagen
Volvo
When you choose your EV in the Ohme app, for every brand supported you’ll be invited to ‘Pair your EV’. Tap continue and read through the introduction screens until you reach the login screen and enter your car app account details.
Once you have logged in, you’ll be able to see the battery level of your car shown on the My EV page.
If for any reason you would like to stop Ohme from being able to retrieve the battery level inside the vehicle you can choose to ‘Unpair your EV’. This will mean Ohme assumes the battery is 0% each time you plug in.
You’ll see the battery level front and centre when a session is in progress. Ohme will check in with your car at regular intervals throughout the session to ensure the target is reached.
We’re always working to offer the latest in technology to our customers. As a part of Ohme Labs, we’re continuously improving this API integration feature and, from time to time, it may not work as intended. Please note, certain functionality may also be limited based on manufacturer-specific API restrictions or limitations.
